The ONBC is excited to announce the upcoming release of three new Natural Home Tour video clips that have been put together by ONBC members, Dawson Willsey, Pat Marcotte and Wintergreen Studios Education and Retreat Centre. These great videos feature many different types of natural buildings, building techniques and alternative technologies - as well as some views of beautiful Ontario forest settings and scenery. 

In keeping with our usual annual Natural Homes Tour date, these videos will be available for viewing starting on Sunday September 26, 2021 on our new YouTube Channel.

A Natural Home Tours Thank You

Over the years, many homes and buildings have participated in our Natural Building Annual tour.

Many of the homes that have been featured were models of innovation and energy efficiency and featured living roofs, natural clay wall finishes, rainwater catchment systems, grey water systems, composting toilets, while others incorporated solar and wind electrical systems, high efficiency wood burning appliances, solar domestic hot water systems, as well as a variety of other interesting green technologies.

The Ontario Natural Building Coalition would like to thank all the volunteer homeowners who have over the years graciously opened their doors and welcomed tour-goers. The annual tour would not be possible without them!
